Abstract

A heated whip hose includes a hose core configured to deliver a fluid, a heating element disposed around the hose core, a protective layer disposed around the heating element and hose core, an insulating layer disposed around the protective layer, and an abrasion protection layer disposed around insulating layer and forming an outer sheath.

First claim

1 . A heated whip hose comprising:
a hose core configured to deliver a fluid; a heating element disposed around the hose core; a protective layer disposed around the heating element and hose core; an insulating layer disposed around the protective layer; and an abrasion protection layer disposed around insulating layer and forming an outer sheath.

2 . The heated whip hose of claim 1 , wherein the hose core comprises a reinforcing material.

3 . The heated whip hose of claim 1 , wherein the protective layer conforms to outer surfaces of the heating element and hose core.

4 . The heated whip hose of claim 3 , wherein the protective layer is a self-vulcanizing high temperature silicone tape.

5 . The heated whip hose 1 , wherein the insulating layer comprises:
a thermal insulating layer formed of a heat-resistant fiber material; and a radiant heat insulating layer disposed around the thermal insulating layer.

6 . The heated whip hose of claim 5 , wherein the insulating layer is an aramid fiber material.

7 . The heated whip hose of claim 5 , wherein the radiant heat insulating layer is a foil-lined polyester tape and wherein a reflective foil surface faces the hose core.

8 . The heated whip hose of 1 , wherein the abrasion protection layer is a polyethylene sleeving.

9 . The heated whip hose of claim 8 , wherein the polyethylene sleeving is a braided tube.

10 . The heated whip hose 1 , wherein the heating element is an electrically conductive wire.

11 . The heated whip hose of claim 10 , wherein the electrically conductive wire is sheathed in ETFE.

12 . The heated whip hose of claim 1 , wherein the heating element is disposed around a partial length of the hose core to form a heated section and an unheated section, wherein the heated section extends from a first end configured to couple to a main hose and wherein the unheated section extends from a second end opposite the first end, the second end configured to couple to a fluid delivery device.

13 . The heated whip hose of claim 12 , wherein the unheated section extends a length up to about 72 inches from the second end of the heated whip hose opposite the first end, the second end configured to couple to a fluid delivery device.

14 . The heated whip hose of claim 12 , wherein the unheated section extends a length less than about 24 inches from the second end.

15 . The heated whip hose of claim 14 , wherein the unheated section extends a length greater than about 6 inches from the second end.

16 . The heated whip hose of claim 12 , wherein the unheated section extends a length of about 12 inches to 18 inches from the second end.

17 . The heated whip hose of claim 12 , wherein the unheated section extends a length selected from the lengths consisting of 6-12 inches, 12.1-18 inches, 18.1-24 inches, 24.1-30 inches, 30.1-36 inches, and 36.1-42 inches from the second end.

18 . The heated whip hose of claim 12 , wherein the heating element is helically wound around the hose core.

19 . The heated whip hose of claim 18 , wherein the heating element is wound with a uniform pitch.

20 . The heated whip hose of claim 18 , wherein the heating element includes a turn at the unheated section, wherein the turn is secured to the hose core.

21 . The heated whip hose of claim 20 , wherein first and second ends of the heating element are located at the first end of the whip hose where the heating element is coupled to an electrical connection.

22 . A heated whip hose assembly comprising a first and a second of the heated whip hose of claim 21 , wherein the second ends of the heating elements of the first and second heated whip hoses are coupled in an electrical connection at the first ends of the whip hoses.

23 . A heated whip hose assembly comprising:
a first whip hose and a second whip hose, each of the first and second whip hoses comprising:
a first end configured to couple to a main hose;
a second end configured to couple to a fluid delivery device;
a hose core configured to deliver a fluid from the first end to the second end;
a heating element disposed around the hose core, wherein the heating element is disposed around a partial length of the hose core forming a heated section and an unheated section, wherein the unheated section is adjacent to the second end;
a protective layer disposed around the heating element and hose core, wherein the protective layer conforms to outer surfaces of the heating element and hose core;
a first insulating layer disposed around the protective layer configured to direct radiant heat from the heating element toward the hose core;
an abrasion protection layer disposed around insulating layer and forming an outer sheath of the whip hose.

24 . The heated whip hose assembly of claim 23 , wherein the unheated section extends a length less than about 23 inches from the second end.

25 . The heated whip hose of claim 23 , wherein the protective layer is discontinued in the unheated section.

26 . The heated whip hose assembly of claim 25 , wherein the heating element has a first electrical connection and a second electrical connection, wherein the first and second electrical connections are located at the first end, and wherein the second electrical connection of the first whip hose is electrically connected to the second electrical connection of the second whip hose.
